From the cricket entry
Wicket Keeper
Often also known as the keeper of the wicket, this is a very important position, especially during Test Matches which often last five days, occasionally with a result. At "Stumps" each day the umpires give the wicket to the wicket keeper to guard, at dawn the next day the wicket keeper must approach the pavilion from where the umpires will shout "Halt, Who goes There" to which the wicket keeper replies "The Keeper of the wicket", "Whose wicket?" respond the umpires; "The Queen's wicket", comes the reply. At this point the umpires allow the wicket keeper to place the wicket back on to the pitch and play starts for lunch.
